2. The dependence on the choice of the gauge condition
(REF ), (e.g., on the parameters \(\beta \) , \(\gamma \)  and
the function \(W(\operatorname{\square })\)  in the weight operator (REF )
is proportional to the effective equations of motion. The same
concerns the dependence of the parametrization of the quantum
metric. In particular, both ambiguities vanish on the classical
mass shell for the one-loop divergences of the effective action.
In what follows (see more details in [1]}) we shall
demonstrate how this feature works in the practical calculations
in QG.
